Nope. It does not fix bug 859287. So it is not a regression. Or at least not the entire reason.

Standard practice throughout the project is to resolve bugs when they hit {comm,mozilla}-central and use the status flags for tracking branch uplifts. Please put checkin-needed back on the bug when it gets approval for aurora uplift.

If the patch is ready, and you want to push this to aurora (or other branch) the correct way is to signal approval-comm-<branch> (set to ?) on the patch.
Then we can come along a approve it. a=me since this is a low risk fix for a regression.
